A few months ago I was making the exact same decision you are right now, I ended up going with the Hornady Lock n Load Classic over the Rockchucker and I'm very happy with it.

I went with the Hornady for 2 reasons,
1. Made in USA (the Rockchucker is not)
2. The lock n load system. Changing dies is effortless and in literally 5 seconds and you're working again.

Also, when I expressed an interest in reloading a firearms instructer and veteran reloader that I know suggested that I start with a single stage press. I'll be honest, I didn't believe him but, through a series of events, I ended up cancelling my order for a Lee loadmaster and getting the Hornady. I can tell you as a new reloader that he, and all the other people who have commented here, are right, you need to start single stage so you can learn how to set each individual die and learn what it feels like to properly (or improperly) seat a primer, crimp a cartridge, etc. You get a lot of tactile feedback from the press that you wouldn't get with a progressive press doing all 4-6 operations simultaneously.
